This
calibration procedure is for maintaining calibration of production
electronic test box ATE-100 on a scheduled basis. If any of the parameters fall
outside these limits, the test box can be recalibrated using trimpots
accessible through the front panel. Calibration should be rechecked every
3-months.

The
1mA for Coil Resistance test and 19.5M resistor calibrations are no longer
required. These functions are for reference only and not to be used to ship
product. For shipping product, use external commercial, off the shelf meters to
measure coil resistance and insulation resistance.

Test Procedure

Plug
in 110 VAC and turn on. All three meters and the green Insulation Resistance
test LED should illuminate.
